The Value of Planning – Questions to first answer are:
What is being protected – Assets?
How important them are?
Do protection costs outweigh the values?
Design-Reference Threat Layer for Protection – follow the principle of security in-depth. Protection must be layered to provide diversity and redundancy, starting with most sensitive point within the facility and work out as:
Physical Barriers – Most be checked at the sensitive areas
Locks – Determine the openings requiring locks
Access Controls – Determine who will be admitted to the facility
Security Force – Determine level of security with appropriate training

The Security or Master Plan and Countermeasures considerations:
Justification – Security plan must be justify to management; hence most management appear to believe security contributes nothing, then, still something happen.
Convincing Oneself That a Proposal is Justified – Security plan must be sound to the designer first to justify the money
Convincing Others It is Justified - Security plan must be sold to others to justify the money
Company’s Experience – A company past experience would make it receptive or not of the plan
Personal Experience – Individual exposure to the issue may draw on previous experience to define and analyze possible ramifications.
Formulating the Approach – Accumulation of raw data would necessity adoption of a strategy for communicating arguments in a convincing manner.
Presenting the Approach – Provide timely Report and present as formulated and included the basic information.
